TREE-SPRAYER.

Specification of Letters Patent.

Patented Sept. 23, 1.913.

Application led May 15, 1911. Serial No. 627,374.

To all whom it may concern Be it known that I, Fonnnsrr G. HAYES, acitizen of the United States, residing at Sharon, in the county ofMercer and btate of Pennsylvania, have invented certain new and usefulImprovements in Tree-Sprayers, of which the following is aspecification.

My invention relates to improvements in a tree sprayer and particularlyto improvements over the structure of a tree sprayer heretofore patentedby myself under U. S. Patent No. 950,916, dated h/larch 1st, 1910. Inthe above patented structure there have been found to be several mattersof detail which were disadvantageous in the practical operation of mytree sprayer. One of these was the manner in which the hose is connectedto the main feed pipe, the arrangement as shown in the prior patentbeing such as to render the operation of my sprayer dif icult, renderingthe ent-ire appliance cumbersome and awkward for handling.

Another feature found desirable and not present in the prior patent isan arrangement by which the nozzle can be pointed in any directionwhatever.

A still further improvement in the present invention resides in themethod of mounting the sliding pipe on the boom and means forfacilitating the turning of the main supply pipe in the supportingbracket heads.

Still further objects and purposes of the present invention will appearfrom an inspection of the drawings, the specification describing thesame, and the claims appended thereto in which are set forth thecombinations of elements, arrangement of parts, and novel structuraldetails properly comprised within the scope of the same.

Referring now to the drawing in which .is shown a preferred constructionof my improved tree sprayer, Figure 1 is a side elevation of my treesprayer constructed in conformity with the improvements contemplated inthe present invention. Fig. 2 1s a plan View of the end portions of thesupply pipe showing the method of operating the nozzle. Fig. 3 is a fullsized side elevation of my bracket and wrench housing showing in thelatter, partially in out-line, my jawed wrench, the boom and supply pipebeing shown in cross section. Fig. 4 is an end elevation of thestructure shown in Fig. 3. Fig. 5 is a fragmentary side elevation of myimproved nozzle showing thereon a sheave by which this nozzle is turned.

In the several figures of the drawing in which like reference charactersdesignate like parts, (5) is the sprayer base having secured thereto awide spread flange (6), with the central boss portion in which thepedestal (7) is mounted. ,Suitably secured to the upper end of thispedestal is a tubular socket (9) in which a member (10) is rotatablymounted, the mounting being such as to permit the mast (13) andstructure carried thereon to be swung in a horizontal plane, relativelyto the pedestal (7). Mounted on the member (l0) is the pulley (11)having a crank arm (11) extending through the lower portion of the mastaffording a bearing therein, the crank arm terminating in the handle(113). rlhe mast (13) is connected to the member (10) by means of a boltfor the purpose of permitting the mast and the structure hinged thereonto be swung in a vertical plane as in the prior patent. Rigidly securedto the mast intermediate the length of the mast is a boom (1T) havingvertically disposed pulleys (39) mounted within the brackets (20) ateither end thereof. For the purpose of strengthening and sustaining theweight of this boom, I provide guy wires (18) connecting the upper endof the mast (1(5) with the inner ends (19) of the pulley brackets (20).In t-he forward part of the boom, I provide two stationary brackets(311; and 311'), the former being positioned near the front end of theboom, and the latter, on that portion of the boom just forward of themast. These brackets are provided with bracket heads in which the supplypipe (32) is adapted to slide. Extending downwardly from the rearportion of the boom, l. have a hanger which is connected by means of aspiral spring (Q4- to the pedestal. Extending downwardly from the hangeris a rope or wire (29) connected at its lower end to a foot pedal (28).The structure thus far described is substantially the same as thatdisclosed in my prior patent.

Intermediate the ends of the supply pipe (32) and between the twostationary brack ets, I provide a T (51) extending from which is aflexible hose (33) connected at its other end to a suitable cock (52).This cock is connected to the upper end of a pipe (53) which issuspended from the pedestal and extends parallel therewith, the lowerend of the pipe being provided with a coupling (54) for connection to afluid supply. Be-

tween the mast and the bracket (34) l secure, by means of ascrew (61)abracket (55) to the boom (17 Referring now to Figs. 3 and 4particularly, it will be seen this bracket comprises the lower portion(59) adapted to closely embrace the boom (17) and to be secured theretoby means of the set screw (61V). Extending upwardly from the lowerportion (59) is an arm having the aperture (58). therein and terminatingin a head (62) consisting of two sides (56) which adord a housing for mywrench.v l provide alined apertures' (57) in the sides (56),

these apertures being of greater diameter f fiinprovements embodied inmy present conjstruction, the operator need not move from liis,positionadjacent the base in order to manipulate all parts of the sprayer.

than my supply pipe (32) which is adapted to rest therein. Seated withinthe wrench housing and loosely embracing the supply pipe is a wrench.(G3)l comprising side inembers which are integrally connected at oneside-for a distance comprising approXi- "boom mounted thereon andadapted to swing in horizontal and vertical planes, a plurality ofbrackets fixed to said boom, a supply pipe slidably mounted on saidbrackets, and means, in one of said brackets, for rotating g said supplypipe.

mately .one half their circumference and terminating in projections.These pro-jections are connected by a rivet in which is journaled thewrench handle (G6) and at the inner end the serrated aw (67 1t will beobserved from this construction that by lifting up the handle (66) thejaw (67 will grasp the supply pipe (32) and a continued lift of thehandle (66) will turn the pipe. Upon releasing the handle, it will, byits own weight, drop against the bracket (55) and the supply pipe, nowsubject only to the weight of the T (51) and the connecting hose willreturn to its initial position. A rope (38) is connected at either endof the supply pipe to the T (51) and` extending through apertures, suchas 58 in the brackets, passes around the end pulleys (39) and around thecrank pulley (14). As in my prior construction, upon turning this handlein one direction, the supply pipe is run outwardly, and in turning thehandle in the other direction, it is returned. TWhile the supply pipe isin the rearmost position, it can be turned in its brackets by graspingthe T (51), but in that this T' is out of reach of the operator when thesupply pipe is run forwardly, l provide my jawed wrench construction tofacilitate the turning of the supply. pipe without necessitating theoperator changing his position relative to the sprayer base; and it willbe readily seen that in my wrench construction, 1 have providedpractical ineans for turning the supi ply pipe, this means beingoperative at a point adjacent the mast and equally effectiveirrespective of the point to which the supply pipe has been slid alongthe boom. The outer end of the supply pipe is bent downwardly and thenparallel to itself, as at 47g, and provided with the elbow (4S) which isconnected to a swivel joint (49) in which the end nozzle (30) is adaptedto turn. Secured to this nozzleis a sheave At the opposite end of thesupply pipe and in a plane parallel to the sheave, l mount the pulley(44) in the bracket (45). A rope,

wire or chain (50) extends about the pulley (44) around the sheave(81).` Mounted on the supply pipe (32) are guides (46) through which therope (50) passes. This rope l which extends along the entire length ofthe supply pipe may be grasped at any point by the operator forthepurpose of rotating the sheave and nozzle therewith.

It will thus be seen that by means of th-e w l claim- 1. A tree sprayercomprising a base, a
